A way to have multiple rust projects in one directory and work with them in a Rakefile

Rakefile.rb

def run(cmd)
  puts "===> #{cmd}"
  system cmd
end

projects = %w(client editor server)

projects.each do |project|
  namespace(project) do
    desc "Cleans the #{project} project"
    task :clean do
      run %Q(cargo clean --manifest-path "./#{project}/Cargo.toml")
    end

    desc "Builds the #{project} project"
    task :build => [:clean] do
      run %Q(cargo build --manifest-path "./#{project}/Cargo.toml")
    end

    desc "Runs the #{project} project"
    task :run => [:clean] do
      run %Q(cargo run --manifest-path "./#{project}/Cargo.toml")
    end

    desc "Tests the #{project} project"
    task :test => [:clean] do
      run %Q(cargo test --manifest-path "./#{project}/Cargo.toml")
    end

    desc "Documents the #{project} project"
    task :doc => [:clean] do
      run %Q(cargo doc --manifest-path "./#{project}/Cargo.toml")
    end
  end
end

namespace :clean do
  desc 'Clean ALL of the projects'
  task :all => projects.map { |p| "#{p}:clean" }
end

namespace :build do
  desc 'Build ALL of the projects'
  task :all => projects.map { |p| "#{p}:build" }
end

namespace :test do
  desc 'Tests ALL of the projects'
  task :all => projects.map { |p| "#{p}:test" }
end
